/**
 * Class {@code PrinterState} is a printing attribute class, an enumeration,
 * that identifies the current state of a printer. Class {@code PrinterState}
 * defines standard printer state values. A Print Service implementation only
 * needs to report those printer states which are appropriate for the particular
 * implementation; it does not have to report every defined printer state. The
 * {@link PrinterStateReasons PrinterStateReasons} attribute augments the
 * {@code PrinterState} attribute to give more detailed information about the
 * printer in given printer state.
 * <p>
 * <b>IPP Compatibility:</b> The category name returned by {@code getName()} is
 * the IPP attribute name. The enumeration's integer value is the IPP enum
 * value. The {@code toString()} method returns the IPP string representation of
 * the attribute value.
